Sunlu Filament Dryer for AMS Bambu Lab (AMS Heater)

Sunlu Filament Dryer for the Bambu Lab AMS

The SUNLU AMS Heater is a smart filament dryer designed specifically as an upgrade for the top cover of the Bambu Lab AMS system (Generation 1). It allows you to dry filament and print simultaneously, eliminating the need for pre-processing the material. Thanks to rapid heating to 70°C in just 20 minutes, an advanced air circulation system, and intelligent humidity monitoring, the device significantly improves print quality. Its compact design, full compatibility with AMS, and support for up to 16 colors make this solution ideal for demanding 3D printing users.

Print and dry simultaneously—save time and achieve better results

Forget about drying filament separately before printing. Thanks to integration with AMS, you can dry the material exactly when you use it. This means stable operating conditions throughout the entire printing process, fewer errors, and higher-quality models without additional steps.

Precise air circulation – even drying without the risk of overheating

A unique air channel system directs heat exactly where it’s needed—around the filament. This ensures effective and even drying while keeping AMS components, such as the feed motor, safe. You minimize the risk of material deformation and component overheating.

Fast heating up to 70°C – ready in minutes

An efficient heating system with PTC technology allows you to reach a temperature of 70°C in about 20 minutes. This is faster than traditional solutions, which translates to greater operational efficiency and shorter wait times before starting a print.

Smart humidity control – filament always in perfect condition

The rH mode automatically monitors humidity levels and reacts in real time. When humidity exceeds the set threshold (50% by default), the device begins drying, and when it drops to around 20%, it switches to standby mode. You can also adjust the range (25–50%) to suit your needs, ensuring optimal conditions for every material.

Easy installation – quick upgrade in 2 minutes

Installing the device is extremely simple and requires no specialized tools or expertise. Just unscrew, mount, and tighten—the entire process takes about 2 minutes. It’s a quick way to improve the performance of your AMS.

More possibilities, less space – ideal for multicolor printing

After installing the AMS Heater, you can use configurations of up to 16 colors without increasing the space required. This is a huge advantage for those working on complex projects and multi-material printing.
